Blend the batter: Add cottage cheese, eggs, almond flour, coconut flour, baking powder, vanilla, sweetener (if using), and salt to a blender.
Blend until completely smooth, about 20–30 seconds. Let the batter rest for 3–5 minutes to thicken slightly.
Preheat the pan: Heat a nonstick skillet or griddle over medium heat. Lightly grease with butter, ghee, or avocado oil.
Test the heat: Flick a tiny drop of water onto the pan; it should sizzle and evaporate quickly.
If it smokes, reduce the heat.
Portion the pancakes: Pour 2–3 tablespoons of batter per pancake. These spread a bit, so keep them small for easy flipping. If adding blueberries, sprinkle a few on each pancake now.
Cook gently: Cook for 2–3 minutes, until bubbles form around the edges and the underside is golden.
Flip carefully and cook another 1–2 minutes. Adjust heat as needed to prevent over-browning.
Keep warm: Transfer cooked pancakes to a low oven (about 200°F / 95°C) while you finish the batch.
Serve: Top with fresh berries, a dollop of Greek yogurt, a pat of butter, sugar-free syrup, or a drizzle of warmed almond butter. For savory, try smoked salmon, chives, and a squeeze of lemon.
